tsc210x cleanup
This is mostly cleanup of the tsc210x patch, but some bugs were fixed so now
it works on tsc2101 too. Also, a few issues are now noted in the code:
Tool-reported:
- Address checkpatch.pl issues in the original patch
- And also "sparse" issues
Previously wrong:
- Cope with CONFIG_SOUND_MODULE
- Register accessor routines will now return error codes
- ... many callers now abort cleanly after errors
- Don't depend on seeing only a rev #1 tsc2102 chip!
- Add missing EXPORT_SYMBOL declarations
Style issues:
- BUG_ON() is strongly to be avoided
- So are macros that capture variables
- And needless casting from void pointers
- And type punning
- Use dev_*() for messaging where practical
- Use u16 not uint16_t, etc
- Various other whitespace issues
- Avoid __FUNCTION__
- Single-lines for file-top comments; no whole paths
Object code size and Other cleanup:
- Compile most strings out unless -DDEBUG is configured (saving space)
- Move some code into exit sections (then it may well vanish, saving space)
- Add some header comments
Open issues:
- Hwmon needs to know VREF and the chip type, and to scale its values
- Upstream push should exclude audio until some version is working
- Audio will needs to export symbols to modules, too
- Lots of the I/O calls (especially audio) still don't handle errors
- How could board init code get board-specific temp calibration data?
Also the Kconfig is more open-ended; tsc210x might in the future include the
tsc2100 and tsc2111, it doesn't need to be limited to tsc2101 and tsc2102.

remove useless/wrong P20_24XX_TSC_IRQ mux
Remove bogus TSC_IRQ pinmux; it's not used, there's no pin
dedicated for touchscreen (or other TSC chip) purposes, and
this doesn't even look right for P20 (0x10b not 0x108, plus
an IRQ would need to be a GPIO i.e. mux 3 not mux 0).

When the OMAP patches are applied and the kernel is built for a
non-ARM target, there are a handful of Kconfig warnings due to the use
of OMAP_MCBSP in arch-independent Kconfig files.
This patch simply removes the 'select OMAP_MCBSP' in these
arch-independent files since it is already 'default y' in

omap2 clock: remove fixed rate from mdm_osc_ck
mdm_osc_ck has a preinitialized rate and is marked as RATE_FIXED, but rather
than using omap2_propagate_rate() as its recalc function, which accounts
for RATE_FIXED clocks, it uses omap2_followparent_recalc(), which sets the
rate to the parent clock's rate. After reviewing the 2430 TRM, fix this
inconsistency by removing the fixed rate declarations (TRM says that this
clock is 'typically' 26MHz).

The rates of some clocks are equal to their parents' rates, divided by some

which follow their parents' rates divided by a runtime-selectable divisor.

Convert omap2_get_clksel to use void __iomem *. Add
omap2_divisor_to_clksel(), to convert clock divisors into appropriate

in clksel code, rather than masks that have been preshifted down to

symbolic constants from the recent PRCM cleanup. Also add code to
